How Cornerstone Plus Works

Cornerstone Plus Herbicide contains glyphosate, a high-potency ingredient for the successful killing of broadleaf weeds and grasses. After spraying, the weed absorbs the herbicide and circulates it throughout the plant and down into the roots. It slowly kills competing weeds that strangle desirable plants and grasses in the same area. You can also use Cornerstone Plus with an adjuvant or a surfactant in the tank for optimal weed performance.

Where to Use Cornerstone Plus Herbicide

Use Cornerstone Plus Herbicide to kill unwanted weeds and grasses on Roundup Ready crops such as canola, cotton and soybean. It also targets weeds in pastures, range lands, greenhouses and shade houses. Apply Cornerstone Plus for habitat management or as an injection for woody brush and trees. It also keeps turfgrass, industrial sites, railroads and roadsides free of weeds.

Target Weeds

Cornerstone Plus Herbicide affects more than 100 broadleaf weeds and grasses. From barnyardgrass to carpetweed, this herbicide works after one spray and kills bothersome weeds where they grow. It also takes out many common weeds such as chickweed, crabgrass and dwarf dandelion. Other target weeds include:

  • Corn speedwell
  • Fleabane
  • Foxtail
  • Henbit
  • Johnsongrass
  • London rocket
  • Pigweed
  • Ragweed
  • Smartgrass
  • Stinkgrass
  • Wheat
  • Witchgrass

Un set completo y efectivo para piel con acné
Este set de The Ordinary me ha funcionado muy bien. Incluye productos que se complementan entre sí, ayudando a reducir granitos, controlar la grasa y mejorar la textura de la piel. Después de unas semanas de uso, noté menos brotes y una piel más uniforme. Me gusta que las fórmulas son sencillas, sin fragancias fuertes, y no me causaron irritación. Es un kit práctico, accesible y con muy buena calidad para quienes buscan mejorar el acné sin gastar demasiado.

Good products but not packaged as a set
I was looking for a gift for my coworker. I thought this was going to come as a set in a box. Not 4 separate items, especially considering the fact that there is a review video posted here that shows a set in a big box together. On closer inspection that review is from a completely different set of Ordinary products not the ones featured in this collection. Why is a review featured for different items? Make it make sense.
